That and self-promotion. Never forget that people like him have a pathological need for attention. It’s pure speculation, but I can imagine that when buying Tesla and promoting it as his own, he expected that he’d be hailed as a savior by those concerned about the climate. When the cracks started to show and the people began to rightfully critize him, he pivoted to another group of rabid fan boys. I would hazard a guess that as long as he gets a steady supply of money and praise, he doesn’t really care about any of the issues he’s currently championing, he just needs someone to make him feel popular. You’d almost pity him, except for the fact that he’s willing to fuck over millions just to feel better about himself… so fuck Musk.
